Abstract

The inventio provides a black matrix and a preparation method thereof, and a display panel. The black matrix is made of a resin composition, the resin composition comprises spiropyrane derivative, bonding resin, photoinitiator, a polymerizable monomer, a shading material, an auxiliary and a solvent. A molecule structural formula of the spiropyrane derivative is as shown in description, wherein R is -CnH2n+1, -CmH2mOH, -Ar or -Ar-CHO, the value of n is 1-20, and the value of m is 1-3. The spiropyrane derivative in the scheme can drive the rearrangement of the polymer chain and the dopant molecular after the structure isomerism occurs, the internal between the black matrix and the substrate is eliminated, and a yield rate of the display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a black matrix, a preparation method thereof, and a display panel. Background technique [0002] At present, a BM (Black Matrix, black matrix) is arranged on a CF (Color Filter, color filter) substrate in a thin film transistor liquid crystal display panel to prevent color mixing between pixels or light leakage at the edge of the CF substrate. With the market's requirements for high-performance products, the line width of BM is getting narrower and narrower, which requires higher and higher optical density values ​​of BM. Generally, the optical density value of BM is increased by increasing the content of carbon in BM. . [0003] However, the reduction of BM line width and the increase of carbon content in BM will lead to a decrease in the adhesion between BM in the TFT liquid crystal display panel, the substrate, and the sealant, which will cause air bubbles to enter the panel...
